INSTALLATION INSTRUCTIONS
2XL-FW503 Rev B
General Safety Information
It is important to read, understand, and follow the important information contained in
these installation instructions. Failure to do so may result in a hazardous condition or
cause a hazardous condition to develop.
All welding should be performed by an AWS certified welder using a low hydrogen
process and AWS E70XX filler metal. Failure to weld correctly may cause distortion,
damage, and/or result in insufficient strength and subsequent joint failure which,
if not avoided, could result in death or serious injury.
Prior to welding take precautions to ensure that the tractor electrical system is not
damaged due to the welding process.
Safety Signal Words
DANGER indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
CAUTION used without the safety alert symbol indicates a potentially
hazardous situation which, if not avoided, may result in property damage.
1. Keep Work Area Clean. Cluttered areas and benches invite accidents.
2. Keep fingers away from all potential pinch points in the fifth wheel.
3. All fifth wheel maintenance must be performed by a qualified service technician
using proper tools and safe procedures.
4. Use only SAF-HOLLAND original parts.
5. Use Safety Goggles. Glasses or goggles not in compliance with ANSI or CSA can
cause serious injury when damaged or broken.
6. Wear Proper Apparel. Do not wear loose clothing, gloves, neckties, jewelry (rings,
wristwatches, etc.) that can get caught in moving parts. Non-slip footwear is
recommended.
Fifth Wheel Design and Intended Use:
1. For pulling trailers with standard SAE kingpins which are in good condition
and securely mounted or locked in position in the trailer.
2. For on-highway hauling applications.
3. Within the capacities stated in SAF-HOLLAND literature.
4. As recommended in SAF-HOLLAND literature (available from www.safholland.us).
Holland Fifth Wheels are NOT Designed or Intended For:
1. Use with non-SAE kingpins, such as kingpins which are bent, improper size or
dimensions, not secured to maintain SAE configuration, or which are installed in
warped trailer bolster plates.
2. Tow-away operations which damage or interfere with the proper operation of
the fifth wheel.
3. The attachment of lifting devices.
4. The transport of loads in excess of rated capacity.
5. Off-highway applications and use.

Installation
General Recommendations
1. Every user and installer using SAF-HOLLAND products either recommended or not
recommended by SAF-HOLLAND,must thoroughly satisfy himself that the installation
procedure used is appropriate for the vehicle, product and application.
2. Consult the SAF-HOLLAND literature for fifth wheel capacities and applications.
3. Consult the tractor manufacturer’s body builder’s book and the latest SAE and D.O.T.
standards for additional installation methods. SAF-HOLLAND recommends the T.M.C.
Recommended Maintenance Practice 603B for installation procedures.
4. Determine the proper fifth wheel position, or, in the case of a sliding fifth wheel, the range of
proper positions. Proper positioning of the fifth wheel is important for weight distribution,
swing clearance and handling characteristics. See SAE J701a for proper placement, as well as
the tractor manufacturer’s body builder’s book.
5. Use Grade 8, 5/8˝ minimum diameter bolts and Grade “C” locknuts for mounting.
6. Bolt holes can be 1/32˝ larger in diameter than the bolt fastener. Bolts must be adequately
tightened using charted torque ranges in foot-pounds for the recommended Grade 8, 5/8˝
diameter bolts. Larger diameter Grade 8 bolts and coated fasteners may be used.
7. The bolts attaching the fifth wheel mounting angles to the truck frame require hardened
steel washers under both the bolt and under the locknut, unless flanged head bolts or
flanged head locknuts are employed.
8. A minimum of 5 bolts are required to attach each mounting angle to a frame rail, and the
distance between bolts must not exceed 8˝, except when cutouts are required in the
mounting angles.
9. Whenever a cutout is made on the mounting angle, such as required to bypass spring
hangers, a 1˝ minimum radius should be used and bolts should be placed within 1-1⁄2˝, but
not closer than 1˝ of the cut, fore and aft.
10. The mounting angle should have a minimum thickness as shown in Chart 1 and should be
steel specification ASTM A 36.
11. When initially positioning the fifth wheel for frame holes, the full length of the fifth wheel or
slider mounting angles should seat flush on the top and side surface of the truck-tractor
frame rails where channel-type rails
are employed. There should not be a
gap over the top of the truck frame
rails. The base of the fifth wheel
assembly and of the mounting angle
members should seat flush on the top
of the frame rail to prevent flexing
and to give uniform weight
distribution. It is also recommended
to chamfer or smooth sharp edges
and corners of mounting materials
wherever contact is made with the
tractor frame.
12. If the fifth wheel is to be mounted using a mounting plate (bracket with mounting base),
refer to CHART 1 for minimum plate thickness recommendations.
Do not use U-bolts in fifth wheel installations. Use only new Grade 8 bolts and
new Grade C lock nuts, sized 5/8˝ minimum diameter. Failure to do so may
result in structural failure of the installation with a potential loss of the fifth wheel assembly,
mounting structure, and/or trailer and may result in death or serious injury.
13. Trailer pick-up ramps are recommended at the rear of the truck-tractor frame.
14. When mounting to aluminum frames, follow the tractor manufacturer’s recommendations.
SAF-HOLLAND has available a stationary mounting angle intended for use with aluminum
frames. Contact SAF-HOLLAND or distributors of Holland brand products for availability.
15. Review, in addition, the specific information on the following pages for each type of fifth
wheel mounting, as well as “Inspection and Lubrication Prior to Use” on page 8 of this
publication.

Bracket with Mounting Angle
(see Figure 1A, 1B, and 1C):
1. Holland brackets with mounting
angle are provided with the bracket
welded in the center of a 36˝ long
angle with a 4˝ minimum
horizontal and 3-1/2˝ minimum
vertical leg size, and to a specific
tractor frame width. Verify that the
bracket and tractor frame width are
the same.
2. In addition to the information
given in “Installation: General
Recommendations” on page 3, follow
the recommendations in FIGURE 1.
Bracket for Angle Mounting
(see Figure 1A, 1B, and 1C):
1. Holland brackets for angle
mounting are intended to be

time of installation.
2. See “Installation: General Recommen-
dations” on page 3, for angle
thickness and material (use 4˝
minimum horizontal and 3-1/2˝
minimum vertical leg size).
The recommended length of
each mounting angle is 36˝. It is
recommended that each angle
extend a minimum length of 18˝ forward of the fifth wheel pivot point, and not less
than 12˝ to the rear. If angles shorter than 36˝ are required, the special
recommendations of the tractor manufacturer should be obtained.
3. In addition to the information given in “Installation: General Recommendations,”
follow the recommendations given in FIGURES 1A, 1B, and 1C. The following
sequence is suggested for both fabricated and cast brackets:
A. Securely position the mounting angle to the tractor frame.
B. Bolt the angles to the tractor as shown in FIGURES 1A and 1B.
C. Position the brackets on the angles and verify the correct spacing to mount
the fifth wheel.
D. For fabricated brackets (a welded asssembly), weld the bracket to the mounting
angle with 1/4˝ fillet welds on both sides, and 1/2˝ groove welds on both ends,
as shown in FIGURES 1A and 1B. The welds should be continuous around the
bracket and joined at the corners.
E. For cast brackets (single piece), weld with 5/16˝ fillet weld, as shown in
FIGURE 1C. The welds must be continuous around the bracket ends.

Sliding Fifth Wheel Installation continued
Adjustment of Sliding Bracket Locking Plungers
The slide locking plungers are given a preliminary adjustment during factory assembly.
However, due to variations introduced during mounting (such as frame and material
tolerances) a final adjustment must be made at the time of installation.
Adjust the locking plungers at installation, after one month of service,
and at recommended maintainence intervals. by use of the adjusting
bolts provided on both sides. Failure to do so may result in accelerated wear of
components, lower service life, improper load transfer, or improper load distribution.
To adjust locking plungers:
1. Loosen lock nut and turn adjusting bolt
out (counterclockwise). See FIGURE 7.
2. Disengage and engage the locking
plungers. Check that the plungers are
securely seated without binding.
3. Turn the adjusting bolt in (clockwise)
until it contacts the rack. Turn the bolt
an additional 1/2 turn then tighten the
locking nut securely.
Prior to proceeding with the installation of the sliding fifth wheel assembly, carefully
review the “General Safety Information” section on page 2.
Installation of Slide Stops
1. It is the responsibility of the installer
to insure that slide stops are installed
properly at all four corners of the
slider plate.
2. Slide the bracket to the full rear
position and engage the plungers in
the rack.
3. Locate rear stops under the curled
edge allowing some clearance to the
bracket (approximately 1/8˝). Clamp
in place. This should position the
stops approximately 1/4˝ to 1/2˝
from the edge of the rear of the plate,
see FIGURES 8A and 8B.
4. Slide bracket ahead out of the way
and weld the stops in place as shown
in FIGURES 8A and 8B. The welds
should be 5/16˝ fillet.
5. Slide the bracket to the full rear
position and check for clearance.
Make sure the plungers on the sliding
bracket seat properly into the rack
with all teeth engaged.

Attachment of Air-Activated Slide Release – If Required
1. Mount the cab control valve in accordance with the instructions provided. It should
be readily accessible to the driver, but protected to prevent accidental activation.
2. Attach an air line, using appropriate fittings to the “air” or “in” port of the valve.
Use an air source recommended by the tractor manufacturer. Use fittings and lines
of suitable pressure rating.
3. Connect an air line between the “cyl” or “out” port of the valve and the active side
of the air cylinder. A bulkhead fitting may be placed at the front of the slide base
plate, if desired. Use fittings and lines of suitable pressure rating and be sure line is
run so as not to interfere with any other operation or component.
4. Check operation of the valve and cylinder.
Inspection and Lubrication Prior to Use
1. Review the installation. Be sure all nuts and bolts are in place and properly
tightened. Be sure all necessary steps were properly followed and that all
components removed to facilitate installation are reinstalled.
2. Check the fifth wheel locking mechanism with a Holland TF-TLN-5001 (2˝) or
TF-TLN-1500 (3-1/2˝) Lock Tester. Examine for proper locking as described in the
“Operating Instructions” of this manual. This must be done to assure that the
mechanism has not been damaged by shipment, handling, or storage.
Failure to properly install, operate, or maintain this fifth wheel could
result in tractor and trailer separation causing death or serious injury
to others.
3. Apply grease to the bearing surface of the support bracket through the grease
fittings on the side or front of the fifth wheel pockets. The top plate must
be lifted up slightly to ensure proper application of grease. (NOTE: This is not
required on Holland LowLube and NoLube top plates.)
4. Apply a generous coating of grease to the top of the fifth wheel plate, where it will
contact the trailer plate. (NOTE: This is not required on Holland LowLube and
NoLube top plates.)
5. Apply a generous coating of grease to the front lock and lock jaws.

3. Grease the support bracket pockets through the
grease fittings on the front of the fifth wheel
bracket pockets (lift up slightly on the fifth
wheel plate when applying grease).
4. For fifth wheels with sliding brackets:
Release and slide fore and aft to assure entire
mechanism functions properly. Apply an aerosol
spray lubricant or soap to the slide path. Apply
Never-Seez™to the plunger and its moving parts.
Reposition and lock sliding mechanism.
5. Inspect the release handle. If your fifth wheel is
a RIGHT HAND (curb side) release, apply grease
along the release handle where it contacts the
handle spring (see Figure 1a). If you have a LEFT
HAND (driver side) release handle with a sliding
spring, as shown in Figure 1b, apply grease
along the release handle where it contacts the
handle spring. Lubrication is NOT required for
LEFT HAND (driver side) release handles that
HAVE a fixed spring (see Figure 1c).
6. Check the operation by locking and unlocking
using a Holland TF-TLN-5001 Lock Adjustment
Tool. Verify that the fifth wheel is completely
closed, as shown in Figure 3A on page 14.

Inspection – Locking Mechanism
1. Check the operation of the fifth wheel
locking mechanism using a Holland
TF-TLN-5001 (2” kingpin) Lock
Adjustment Tool. Inspect for proper
locking as described in the “Fifth
Wheel Operating Instructions” section of
this manual.
2. IMPORTANT! The lock is properly
closed when:
Required Inspections and
Adjustments
Perform the following every six months
or 60,000 miles, whichever comes first.
Thoroughly steam clean all components
before inspecting or adjusting.
General Fifth Wheel Inspection:
1. Inspect the fifth wheel mounting.
Check torque and replace any missing
or damaged bolts. Check for broken,
worn or damaged parts, replace as
needed.
2. Thoroughly clean the fifth wheel
locking mechanism every 6 months or
60,000 miles and relubricate (see
Figure 1 on page 15). Re-check
operation with TF-TLN-5001 Lock
Adjustment Tool.
3. Inspect the fifth wheel for bent, worn
or broken parts. Replace with Holland
parts only.
4. Make sure the bracket pin retention
bolts and locknuts are in place and
tight, as shown in Figure 2.
Do not use any fifth wheel
that does not operate
properly. If your fifth wheel does not
operate properly, contact your nearest
Holland representative for assistance.
Failure to properly operate this fifth wheel
could result in tractor and trailer separation
and may cause injury or death to others.

Adjustment – Locking Mechanism:
1. Using ONLY a Holland TF-TLN-5001
Lock Adjustment Tool, lock the fifth
wheel.
2. Check the plunger – it must be
visible behind the lock and
engaged on both steps, as shown in
Figure 3A. If the plunger is not visible
or not engaged on both steps (Figure
3B), turn the adjustment bolt
counterclockwise 1/2 turn, then try to
lock the locks again.
3. Check the release handle – it must
be fully retracted and the handle lock
notch must be behind the rib as
shown in Figure 3C.
4. Using a 15/16” socket, tighten the
locks by turning the lock adjustment
bolt clockwise 1/4 turn at a time.
Remove the socket wrench from the
bolt and rotate the lock adjustment
tool, as shown in Figure 4, to check for
resistance between the lock and lock
adjustment tool.
5. Continue to alternate tightening
(clockwise) the adjustment bolt 1/4
turn at a time, removing the socket
wrench, and rotating the lock
adjustment tool until you feel
resistance against the lock adjustment
tool. Once you begin to feel resistance,
STOP!
At this point, the fifth
wheel is OVERADJUSTED
and NOT useable. Using an improperly
adjusted fifth wheel could result in
tractor and trailer separation and may
cause injury or death to others.
6. Loosen the adjustment bolt counter-
clockwise TWO FULL TURNS. The lock
is now properly adjusted.
7. Verify this adjustment by locking and
unlocking several times using the Lock
Adjustment Tool; check for proper
locking (See Figure 3A and Figure 3C).
8. If there is a large amount of fore and
aft movement with the adjustment
tool when verifying adjustment, check
to make sure the lock is engaged in
both steps (Figure 2).
If the lock is only engaged on one
step, repeat Step 2 (above), of the
Adjustment Procedure until the lock
engages on both steps. (See Figure 3A.)
Improper adjustment can
cause improper locking
of the fifth wheel which could result in
tractor and trailer separation and may
cause injury or death to others. If the
fifth wheel does not operate properly,
DO NOT USE IT! Repeat the adjustment
procedures or contact your local Holland
representative for assistance.

Adjustment – Fifth Wheel Slide
Mechanism
1. Loosen lock nut and turn adjustment
bolt out (counter-clockwise).
2. Disengage and engage the locking
plungers. Verify that plungers have
seated properly as shown.
3. Now tighten adjustment bolt until it
contacts the rack.
4. Turn the adjustment bolt clockwise an
additional 1/2 turn, then tighten the
lock nut securely.
5. If plungers do not release fully to
allow fifth wheel to slide:
a. Check the air cylinder for proper
operation. Replace if necessary.
b. Check plunger adjustment, as
explained above.
c. If a plunger is binding on the
plunger pocket, remove the plunger
using a Holland TF-TLN-2500
spring compressor. Grind the top
edges of the plunger 1/16˝ as
shown. Re-install and adjust the
plungers, as explained above.
Proper adjustment of the
locking plungers must be
performed at regular intervals and is
required for proper operatiion, load
transfer and distribution.
6. If the locking plungers are too loose:
a. Check plunger adjustment, as
explained above.
b. Check plunger springs for proper
compression. Replace if necessary.
c. Check for plunger wear. If
necessary, replace, as described
above.
After inspection and adjustment, relubricate
all moving parts with a light, rust resistant
oil.
